1 Collaborative Laboratory Commissioning and Sustaining the Optimal Building By E. Lon Brightbill, P.E Facility Dynamics

2 Overview DefineCommissioning (Cx) Put the Cx process in the Context of a State of the Art Laboratory Facility (NIH B50) Present a software tool (ComIT) that facilitates a collaborative, paperless Cx process and provides an operator interface to building information Review laboratory functional performance testing Discuss Getting the Most From Cx and how to Sustain it Present a tool for continuous commissioning (PACRAT)

and provides an operator interface to building information Review laboratory functional performance

3 Commissioning The systematic process of ensuring that all building systems perform interactively according to the design intent and the Owner s operational needs. All design/construct parties collaborate Begins in planning stages and proceeds into occupancy

intent and the Owner s operational needs.

4 Commissioning Goals Ensure facilities are designed to meet Owner s needs Ensure facilities are installed properly Ensure intent and installation are fully documented Ensure Operators are fully trained Facilities are optimized for the actual occupancy

intent and installation are fully documented Ensure Operators
